Russian-Ukrainian Dnepr to fly in the midst of political crisis

As Russia and Ukraine are locked in the most serious political crisis and the military confrontation since the end of the USSR, specialists from both sides launched a converted Soviet ballistic missile originally built in Ukraine.

Previous chapter: The 19th mission of the Dnepr rocket

The liftoff of the 20th Dnepr rocket, took place as scheduled on June 19, 2014, at 23:11:11 Moscow Summer Time (3:11 p.m. EST) from an underground silo facility No. 370/13 in the Dombarosvsky ICBM deployment area in southern Russia.

The rocket carried the KazEOSat-2 (DZZ-MRES) remote-sensing satellite for the imaging of the Earth surface, which was built by the European consortium Airbus Defense and Space for the government of Kazakhstan and a cluster of 36 secondary payloads for customers from 17 countries, including Deimos-2, Hodoyoshi-3, Hodoyoshi-4, BugSat-1, SaudiSat-4, AprizeSat-9, AprizeSat-10, UniSat-6, Tigrisat, AeroCube 6, ANTELSAT, Lemur-1, BRITE-CA 1, BRITE-CA 2, NanosatC-Br1, Duchifat-1, Perseus-M1, Perseus-M2, QB50P1, QB50P, Tablesat-Avrora, 11 satellites Flock-1c, POPSAT-HIP 1, PACE, PolyITAN, DTUSat-2.

Flight profile

Following the blastoff from its launch silo, the Dnepr headed south to enter an orbit with an inclination 97.9 degrees toward the Equator. After separation of two lower stages of the launch vehicle, the payload section turned 180 degrees and continued its ascent with the help of low-thrust engines. The top section of the payload fairing then separated allowing payloads to be released from the back side of the carrier vehicle one after another around every two seconds, while the third stage continued the powered flight between 950th and 972nd seconds of the flight.

Release sequence in the 20th Dnepr mission:

Satellite	Time from launch
BugSat-1	950 seconds
Tablesat-Avrora	952 seconds
Deimos-2	954 seconds
A platform and five QuadPack carriers	956 seconds
KazEOSat-2	958 seconds
Hodoyoshi-4	960 seconds
Hodoyoshi-3	961 seconds
SaudiSat-4	962.5 seconds
UniSat-6	964 seconds
AprizeSat-9	965.5 seconds
AprizeSat-10	967 seconds
BRITE-Toronto	970 seconds
BRITE-Montreal	972 seconds
